Yes, I have spent some time in GITMO. I served in Navy ships that went there for training. The training is called refresher training...or REFTRA and it lasts about two months. It is the most intensive ball busting you can imagine. A ship reporting there "chops" to the commodore of the Fleet Training Group and comes under his and his staff's control. The staff is made up of a bunch of senior petty officers (E-6 to E-9, with heavy emphasis on the 7s & 8s) and warrants and LDOs with years of experience. They drill the ship 18-24 hours a day, six days a week, in all types of combat operations, damage control, fire fighting, missile shooting, gunnery, you name it...you get hit with it there. Because the ships are far from homeport, the ship devote virtually all of its time "training". No going home at night for a squeeze and a beer.
The base is actually a fairly big piece of land ceded to the United States by a 99 year treaty. Castro hasn't had the balls or the ability to abrogate it and kick us out yet. It must really give him a daily redass to have us down there too.
The base is pretty big. It's on the leeward side of Cuba and is hot and relatively humid year round. Surrounding the base used to be a very tall fence with guard towers every few hundred yards...but these were not all manned when I was there because the tensions between us the the Cubans was low. In fact lots of then worked on the base. Great source of income for those poor people. The Cubans likewise have their fence a couple of hundred yards away from ours. The "no-mans-land" in between is (was?) seeded with thousands of mines. When I was there last, the permanent party personnel were all integrated into the defense team; Navy folks too. Dependents were allowed to move down after an extended period of time and when housing became available. The base had virtually all of the usual stuff you find at any military installation such as clubs, a commissary, mini-marts, gas station, package store and PX. Funny...there were goats running around all over the place.
A bit of strange history: Back in the early sixties, after the Cuban revolution, Castro tried to run us out by cutting off our water supply, the source of which was outside the fence. Remember, this was after the Bay of Pigs...and after we tried to assassinate the commie bastard. When he shut down the water, Navy ships at first helped supply emergency water, but the [semi] permanent fix was for the Navy to bring down a small nuclear reactor distilling plant. Once that got on line and pumping out water...Castro gave up and turned the water back on. The CO then was a CMH awardee by the name of John D. Bulkeley. If you ever saw the movie, "They Were Expendable", Robert Montgomery played the part of the PT squadron CO, LCDR Bulkeley. I met Bulkeley in 1970 when he was a two star. My eyes immediately locked onto the sky-blue ribbon with the five white stars at the top of his chest spinach...and it clicked...I had read the book and seen the movie as a kid...I had also seen the message saying he would be aboard that day but I had not put two and two together yet. This guy was a boyhood hero of mine...cool. Tough old bird though.
I have not been down there in several years. I know nothing about the POW camps.
I just remember that it was hot and there wasn't a whole lot to do there except go to the club, get stewed and wish you were back in the world.
